Based on the above-mentioned mobile terminal hardware structure and communication device structure, various embodiments of the projection method of the mobile terminal of the present invention are proposed.

3, the present invention provides a projection method of a mobile terminal. In the first embodiment of the projection method of the mobile terminal, the projection method of the mobile terminal includes:

Step S10, after determining that the original projection file is sent to the receiving end, send a request instruction to the receiving end to request to start the projection operation, wherein the original projection file is used as the to-be-projected file of the receiving end;

With the increasing popularity of mobile terminals, mobile terminals have increasingly become an indispensable part of people's work and life. One of the usage scenarios is that users in different regions need to hold a meeting to discuss the same file. At this time, for the convenience of the user and saving the user's time cost, the file and the user's operations on the file can be processed through the mobile terminal. projection to achieve. The mobile terminal may be a smart phone, or a terminal with a display device such as a tablet computer, and the file may be a document file in various formats such as a word document, a pdf document, or a video file. Understandably, when a mobile terminal performs projection, the number of mobile terminals is at least two, one of which is used as a transmitter and the other is used as a receiver. The mobile terminal projection method in this embodiment is mainly applied to a mobile terminal as a transmitter. The sending end includes the original projection file to be projected, and the original projection file is sent to the receiving end as a file to be projected for projection. Specifically, a direct or indirect communication connection is established between the sending end and the receiving end. When the direct communication connection is made, the direct transmission communication between the sending end and the receiving end can be carried out by means of WIFI or data traffic; when the indirect communication connection is made , the indirect transmission communication between the sender and the receiver can be carried out through the cloud. Before starting the projection operation, the original projection file that needs to be projected is sent to the receiving end in advance. After receiving the original projection file, the receiving end caches the original projection file as the file to be projected, so that when the projection starts, the The file to be projected is projected. After monitoring the completion of sending the original projection file and determining that the original projection file is sent to the receiving end, a request instruction is sent to the receiving end to request the projection to operate.

Step S20, receiving the operation instruction sent by the user based on the original projection file after receiving the determination information for determining to start the projection operation;

Further, after the sending end sends the original projection file to the receiving end in advance, if no projection operation is required between the sending end and the receiving end, neither the sending end nor the receiving end performs the next step. When a projection operation is required, a request command for starting projection is sent to the receiving end, and the receiving end returns confirmation information to the request command, and this confirmation information is used as the start projection operation for enabling projection. When the determination information is received, the projection is started, and the operation instruction sent by the user based on the original projection file is received. Specifically, the operation instruction is made for the original projection file. When the original projection file is a video file, the operation instruction may include playing, pausing, fast forwarding or rewinding the video file, etc. When the original projection file is a document file, the operation instruction It can be sliding the document, or adding annotation information to the document, etc.

Step S30, the operation instruction is sent to the receiving end, so that the receiving end displays the operation instruction on the file to be projected, and the location where the operation instruction is displayed on the file to be projected corresponds to the location displayed on the original projected file.

Further, after receiving the operation instruction sent by the user based on the original projection file, the received operation instruction is sent to the receiving end, and the receiving end displays the received operation instruction on the to-be-projected file. In addition, in order to realize projection, the content of the original projection file displayed by the sending end and the content of the to-be-projected file displayed by the receiving end should be consistent, and the display position of the operation instruction in the to-be-projected file corresponds to its display position in the original projection file, so that Keep the projection content of the sender and receiver consistent. The corresponding manner may be determined by the display attributes of the display devices at the sending end and the receiving end, or may be determined by the projection content.

Understandably, the sending end and the receiving end belong to different mobile terminals, and the display properties of the display device used to realize the display function of the mobile terminal may be the same or different, and the display properties may include the display size of the display device or the pixel size of the display device. Wait. Regardless of whether the display attributes are the same, first determine the type of the operation instruction, and then convert the position of the operation instruction in the original projection file to the position of the operation instruction in the to-be-projected file. The size and the size ratio of the receiving end display device are carried out. For example, the operation command is the key point of marking, and it occurs at the top-to-bottom third position of the display device on the sending end, then after receiving the operation command, the receiving end first analyzes and determines that the operation command is the key point of marking, and at the same time determines the The operation instruction occurs at the top-to-bottom third position of the display device at the sending end, so that the key-marked operation instruction is displayed at the top-to-bottom third position of the display device at the receiving end displaying the file to be projected. When the projection content is determined, for the video document, the type of the operation instruction is determined first, and then the time point at which the operation occurs is determined. For example, for a certain video file, the type of operation instruction is pause, and the pause time point is three minutes and thirty seconds of the video; when the receiver receives this operation instruction, it first analyzes that the operation instruction is a pause operation, and pauses The position of the video file is 3 minutes and 30 seconds of the video, so the pause operation is performed at 3 minutes and 30 seconds of the video file received by the receiver. For the document file, first determine the type of the operation instruction, and then determine the position of the operation instruction by determining the number of lines of the document where the operation instruction occurs. For example, for a pdf file, the operation command is slide, the initial position of the slide is on the 12th line of the original projection file, and the end position is on the 15th line of the original projection file, then the corresponding line 12 to 15 of the file to be projected Swipe between. By corresponding the position displayed in the file to be projected and the position displayed on the original projected file, the consistency of the displayed contents of the sender and the receiver is finally achieved. In this embodiment, when the mobile terminal is projected, an audio call can also be performed, so that the user can explain or discuss the projected content of the transmitting end and the receiving end. Call function, which is not limited.

In the projection method of the mobile terminal according to the technical solution of the present invention, after it is determined to send the original projection file to the receiving end, a request instruction is sent to the receiving end to request to start the projection operation, wherein the original projection file is used as the to-be-projected file of the receiving end; After determining the information for starting the projection operation, receive the operation instruction sent by the user based on the original projection file; send the operation instruction to the receiving end, so that the receiving end can display the operation instruction on the to-be-projected file, and the operation instruction is to be projected on the to-be-projected file. The file is displayed in a position corresponding to the position displayed on the original projected file. In this scheme, after it is determined that the original projection file that needs to be projected is sent to the receiving end as the to-be-projected file of the receiving end, a request instruction for starting the projection operation is sent, and after it is determined to start the projection operation, the operation instruction sent by the user based on the original projection file is sent. to the receiving end, so that the receiving end displays the operation instruction on the projection file, and the display position corresponds to the display position on the original projection file. Thus, the real-time transmission and display of the original projection file by the sender and the receiver are avoided, and the consumption of traffic resources for projection by the receiver and the sender at any time and anywhere is reduced.

Further, referring to FIG. 4 , on the basis of the first embodiment of the projection method of the mobile terminal of the present invention, a second embodiment of the projection method of the mobile terminal of the present invention is proposed. After starting the determination information of the projection operation, the step of receiving the operation instruction sent by the user based on the original projection file includes:

Step S40, judging whether the receiving end has successfully received the original projection file;

Step S50, when the receiving end successfully receives the original projection file, the step of sending the operation instruction to the receiving end is performed;

In step S60, when the receiving end fails to receive the original projection file, the projection image of the original projection file and the original projection file are sent to the receiving end.

Understandably, when sending the original projection file to the receiving end, the receiving end may fail to receive, or the sending end may fail to send, so that after the projection operation is started, the receiving end does not have the original projection file, so that the sending end and the receiving end cannot The content of the end projection is inconsistent, and users cannot communicate effectively.
